Nasopharyngeal angiofibroma. surgical approach using a transoral Le Fort I osteotomy following embolization: a case report.
Nasopharyngeal angiofibroma (NA) is a rare vascular benign nonencapsulated neoplasm, characterized by local aggressiveness and destructive potential, typically diagnosed in adolescent males. We report a case of NA affecting a 15-year-old male that presented with a persistent nasal obstruction and epistaxis with 1 year of evolution. Clinical and radiological patterns pointed out a differential diagnosis of NA. Arteriography demonstrates the vascular support of the tumor and evinces the embolization of the internal maxillary artery. The surgical approach was procedure by Le Fort I osteotomy exposing the tumor and promoting easy access for posterior removal. The surgery was carried out without hemorrhagic problems. The maxilla was fixed in the original position with 4 L-shape plaques. Histopathological findings supported the diagnosis of NA. The patient presented after 8 months of postoperative follow-up, without clinical signs of recurrence or residual tumor and without palatal or maxillary teeth paresthesia.
